# Viewing your Prometheus metrics
<a name="ContainerInsights-Prometheus-viewmetrics"></a>

You can monitor and alarm on all your Prometheus metrics including the curated pre-aggregated metrics from App Mesh, NGINX, Java/JMX, Memcached, and HAProxy, and any other manually configured Prometheus exporter you may have added. For more information about collecting metrics from other Prometheus exporters, see [Tutorial for adding a new Prometheus scrape target: Prometheus API Server metrics](ContainerInsights-Prometheus-Setup-configure.md#ContainerInsights-Prometheus-Setup-new-exporters).

In the CloudWatch console, Container Insights provides the following pre-built reports: 
+ For Amazon EKS and Kubernetes clusters, there are pre-built reports for App Mesh, NGINX, HAPROXY, Memcached, and Java/JMX.
+ For Amazon ECS clusters, there are pre-built reports for App Mesh and Java/JMX.

Container Insights also provides custom dashboards for each of the workloads that Container Insights collects curated metrics from. You can download these dashboards from GitHub
